Note that the card reader, various interface circuits, the power supply circuit, and the like are not shown in FIG. The gas wireless meter 1 normally uses a built-in battery as a power source, but a DC12V power source obtained from a car cigarette lighter or the like can also be used.

This gas wireless meter 1 has a "meter reading",
Five kinds of functions of "inspection", "setting", ID setting, and ID change are set. By using one gas wireless meter detector 1, meter reading, inspection and setting, and ID of each device Settings and ID changes are possible.

In the meter reading function, the microcomputer gas meter 3 regularly sends a gas usage amount collected in the memory and stored in its memory, that is, a request for sending meter reading data to the microcomputer gas meter 3, and in response thereto, the microcomputer When the meter reading data of the gas meter 3 is transmitted, the data is received and a process of storing it in the customer memory card 15 is executed.

In the inspection function, similarly to the meter reading function, a request for sending out inspection data, which is periodically collected by the microcomputer gas meter 3 side and stored in the memory thereof, is transmitted to the microcomputer gas meter 3, and in response to this request. Microcomputer gas meter 3
When the inspection data is transmitted, the inspection data is received and stored in the customer memory card 15.

With the setting function, for example, when a new large gas appliance is purchased and the amount of gas used is greatly increased and the set value of the microcomputer gas meter 3 is changed, the set value data is transmitted. To change the setting value of the microcomputer gas meter 3. Similarly, when a new set value is input, the set value data is transmitted and set in the microcomputer gas meter 3.

The ID setting function sets each ID code of the microcomputer gas meter 3, the gas leak alarm device 5 and the alarm display plate 7. In this case, the ID code of the device itself and the ID code of the device to which the device is connected are registered.

The ID changing function is used when the connected device is changed by newly changing the once set ID code. For example, if it becomes necessary to replace one of the devices that make up the system, if the ID registration in the other device that is the communication target of this device must be changed to that of the new device. used.

The customer memory card 15 stores various information about the customer together with a unique ID code.

The radio 3A of the microcomputer gas meter 3 has a function of receiving a command to the microcomputer gas meter 3 and transmitting data output from the microcomputer gas meter 3. To outline its function, this radio 3A
Is operated by a built-in battery and normally waits for a command from the gas wireless meter reading device 1, which is the parent device, in a nap state, that is, in a state in which power consumption is suppressed. Then, after receiving the interrogation of the gas wireless meter 1 and confirming that it is an interrogation to itself, it responds to the gas wireless meter 1. Next, after the microcomputer gas meter 3 is activated to make it possible to exchange information, a command from the wireless gas meter 1 is transmitted. Further, the response data from the microcomputer gas meter 3 is transmitted to the gas wireless meter reading device 1. Then, when the communication completion command is received from the gas wireless meter 1, the initial nap state is restored.

The gas leak alarm device 5 is installed at a predetermined location near each gas appliance, and when a gas leak is detected, the detected data is supplied to the memory of the microcomputer gas meter 3.

The alarm display plate 7 receives each data of the microcomputer gas meter 3 and the gas leak alarm device 5 and displays the received data or a result calculated based on the received data. It has a function of giving a gas cutoff instruction to the microcomputer gas meter 3 based on the alarm signal of.

Next, the operating procedure of the gas wireless meter 1 according to this embodiment will be systematically described with reference to the flow charts of FIGS.

First, when the gas wireless meter 1 is turned on and any one of "meter reading", "check", "setting" and "composite" is selected as shown in FIG. The processing of the selected item is executed as follows. Since each item is displayed, the meter reader presses any one of the three items to select it (steps 301 to 315).

<Metering Process> FIG. 5 shows the procedure of the metering process. The meter reader selects individual slave units (abbreviated as individual),
Select either the batch selection of slave units (abbreviated as batch) or the meter number designation (abbreviated as required). Here, "individual selection of a child device" means that meter numbers are taken out one by one from the customer memory card 15 and each meter reading target is designated. Further, "collection of slave units" means that meter numbers are sequentially taken out from the customer memory card 15 and the meter reading targets are designated collectively. Furthermore, the "meter number designation" is also called "as-needed" designation. Instead of reading the meter number from the customer memory card 15, the meter-reader inputs the meter number each time at the site and designates the meter-reading target. Say that.

When "individual" is selected, one meter number is extracted from the customer memory card 15 and stored in the read command memory of the memory section 11B (steps 503 and 505). Further, when "collective" is selected, the meter numbers are sequentially taken out from the customer memory card 15 and stored in the read command memory of the memory section 11B (steps 507 and 509). Further, when "as needed" is selected, the meter number designated by the key is stored in the read command memory of the memory section 11B (steps 511, 513).

<< Communication Procedure >> In this way, the "meter reading" is selected, and any one of the individual, collective and occasional processing is designated from the selection, and then the read key is pressed (FIG. 3). 317) and the microcomputer gas meter 3 to be transmitted is confirmed (step 319),
A meter reading command is transmitted to the microcomputer gas meter 3 (step 401 in FIG. 4).

Each microcomputer gas meter 3 monitors the data transmission from the meter 1 and receives a read command with its own ID code (step 431YE).
S) and A to the gas wireless meter 1 for confirmation of reception
After transmitting the CK signal, meter reading processing is executed (steps 433 and 435). When the meter is accurately read, this read data is transmitted to the gas wireless meter reading device 1. If a reading error occurs and the meter cannot be read accurately, an error is input to the reading memory in the microcomputer gas meter 3, and the error is transmitted to the gas wireless meter 1 (steps 437 to 441). ).

On the other hand, the gas wireless meter 1 side monitors the reception of the ACK signal, and if the ACK signal is not received, it is determined whether or not there is a communication error (step 40).
3). It is determined that there is a communication error (step 403YE
S) and the number of the gas meter 3 to which the ACK signal has not been transmitted are stored in the communication abnormality memory in the memory unit 11B (step 405), and then the process is terminated. On the other hand, if the ACK signal is correctly received and the communication abnormality has not occurred (NO in step 403), the process then shifts to the data reception standby state. Then, when the data is received, the received data is temporarily stored, and then a response is transmitted to the microcomputer gas meter 3 side and the reading completion display is displayed on the liquid crystal display 13 (steps 407 to 413). The microcomputer gas meter 3 side is waiting for the reception of this response, and when the response is received (step 443 YES
), The processing ends.

In addition, the gas wireless meter 1 executes a process of storing the received data in the customer memory card 15 (steps 415 to 421).

As described above, in the present embodiment, it is possible to wirelessly suck up the meter reading data of each microcomputer gas meter 3 by using the gas wireless meter reading device 1.

<Inspection Process> FIG. 6 shows the procedure of the inspection process.

Similar to the above-described meter reading processing, first, a meter reading operator touches the touch panel 13 "individually" or "as needed".
Or "collective" is selected and input.

In the case of "individual", one meter number is taken out from the customer memory card 15, and the memory section 11B
Stored in the read command memory within (step 60).
3, 605).

In the case of "collective", meter numbers are sequentially taken out from the customer memory card 15 and stored in the read command memory in the memory section 11B (steps 607, 609).

Further, in the case of "each time", the meter number inputted from the touch panel 13 is stored in the read command memory in the memory section 11B (step 611,
613).

In this way, when the meter number is stored in the read command memory in the memory section 11B, the inspection item is next input from the touch panel 13. The inspection item is
In the case of the leakage inspection, "leakage inspection" is set in the read command memory in the CPU 1 (steps 619 and 62).
1). In the case of abnormality inspection, "abnormality inspection" is set (steps 623 and 625). In the case of the shutoff valve opening / closing inspection, "shutoff valve opening / closing inspection" is set (step 62).
7, 629).

<< In Case of Shutoff Valve Open / Close Inspection >> The shutoff valve open / close inspection will be described in detail. In this shutoff valve open / close inspection, as shown in FIG. 7, first, whether the shutoff valve is open or closed. Is determined (step 701), and if it is an open inspection, the process proceeds to step 703 and thereafter.

In the open inspection, the valve open command is sent to the microcomputer gas meter 3 side only when the current valve state is "valve closed" and when "valve open" is permitted (steps 703 and 705). It is output (step 707). When a valve open signal indicating that the "valve open" has been executed is received from the microcomputer gas meter 3 side in response to the valve open command, this is stored in the customer memory card 15 (step 70).
9, 711).

On the other hand, in the case of the closed inspection, in order to prevent accidentally shutting off the gas in use, it is first inspected whether or not the gas is currently in use (step 713). If it is in use, the valve close check is not performed. If no gas is currently used, the valve close command is issued by the microcomputer gas meter 3.
To the side (step 715).

In response to the valve closing command, the microcomputer gas meter 3
When the valve closing process is executed, the microcomputer gas meter 3 transmits a valve closing signal indicating that the "valve closing" has been executed. When the needle detector 1 receives this valve closing signal, the content is stored in the customer memory card 15 (step 71).
7, 711). Of course, after the inspection and inspection, step 70
The process from 1 to step 707 is executed to output the valve opening command to open the valve.

As described above, according to the present embodiment, the open / close inspection of the shutoff valve of the microcomputer gas meter 3 can be performed wirelessly from the gas wireless meter 1 and the execution data thereof can be received. Further, prior to execution of the opening / closing inspection, the current state is surely grasped and then executed, so that it is possible to prevent the occurrence of troubles due to erroneous operations.

<Setting Process> FIG. 8 shows the procedure of the setting process.

The microcomputer gas meter 3 has various "setting" items according to the environment in which it is used. For example, the number and type of gas appliances (whether or not there is a gas bath or gas stove, etc.) vary depending on the home. Therefore, when using the gas meter, it is necessary to input the setting values for these items in advance. If this setting value is not entered correctly, even if there is no gas leak,
Problems such as closing the shutoff valve upon recognizing a gas leak will occur.

In the case of newly inputting the setting and changing the setting of the already set item, the following processing is executed.

As shown in FIG. 8, it is possible to select "individual", "every time", or "collective" as in the case of the meter-reading processing and inspection processing. Select one of ".

When "individual" is selected, one meter number is taken out from the customer memory card 15 and stored in the read command memory of the memory section 11B (steps 803 and 805). Further, when "Batch" is selected, the meter numbers are sequentially taken out from the customer memory card 15 and stored in the read command memory of the memory section 11B (steps 807 and 809). For example, when changing the size of a gas cylinder in an entire area, select all gas users (contractors) in that area at once,
It is very convenient when you want to change the setting items at once. Further, when "as needed" is selected, the meter number designated by the key is stored in the read command memory of the memory section 11B (steps 811 and 813).
When changing the settings of one microcomputer gas meter 3, etc., "every time" or "individually" is convenient.

Next, it is judged whether the setting is changed or the setting item is confirmed. If the setting item is changed, the setting of the corresponding item is changed and stored in the write command memory of the memory section 11B. If only confirmation is required, confirmation items are set in the memory (steps 819 to 825).

<< Setting Change Processing >> When the data is confirmed to be abnormal and the abnormality is recovered by changing the setting, the setting is changed by the setting change key. In this case, the processing shown in FIG. 9 is executed.

First, a write command for a preset setting value is generated and written in the write command memory of the memory section 11B (step 903). Then, after instructing the number of the corresponding gas meter 3, the write key is pressed down (steps 905 and 907). Then, after confirming the partner radio, a meter write command is transmitted (step 911).

The microcomputer gas meter 3, which has received the meter write command, transmits the ACK signal and then executes the process of writing the received setting data (step 93).
1-935). Further, it is checked whether or not this write data has been read and correctly written (step 93).
7, 939). When it is confirmed that the data has been written correctly, a response is sent to the gas wireless meter 1 (step 941). On the other hand, in the gas wireless meter 1
When this response is received, the set value of the read data is changed, and then the read data is stored in the customer memory card 15 (steps 915 to 919), and the processing is ended.

As described above, in the present embodiment, when the meter reading data is confirmed and there is a data abnormality due to improper setting of the microcomputer gas meter 3, the setting changing function of the gas wireless meter reading device 1 is performed. This can be dealt with by changing the setting using. Therefore, unlike the conventional case, it is not necessary to separately prepare a setting device in addition to the meter-reading device, which enables not only quick response but also operation of the gas meter-reading operation with a small equipment investment.

<Composite Processing> Complex processing means collectively performing processing for reading setting data and sucking up inspection data while executing meter reading processing. The processing procedure is shown in the flowchart of the figure.

As shown in FIG. 10, this composite processing also
It is possible to select three processing methods, "individual", "as needed", and "collective", and each processing is the same as that described above.

That is, when "individual" is selected, one meter number is extracted from the customer memory card 15 and stored in the read command memory of the memory section 11B (steps 1003 and 1005). If "Batch" is selected, the customer memory card 1
The meter number is fetched from 5 and stored in the read command memory of the memory unit 11B (steps 1007, 1).
009). Further, when "as needed" is selected, the meter number designated by the key is stored in the read command memory of the memory section 11B (steps 1011 and 1).
013).

Thus, when the meter number is stored in the read command memory in the memory section 11B, the inspection item is next input from the touch panel 13. The inspection item is
In the case of the leakage inspection, "leakage inspection" is set in the read command memory in the memory unit 11B (step 101).
9, 1021). In the case of abnormality inspection, "abnormality inspection" is set (steps 1023 and 1025). And
All the setting data are input to the read command memory of the memory unit 11B (step 1027).

In this way, when the composite setting process is executed,
The processes after step 317 in FIG. 3 are executed to carry out the combined process.

As described above, according to the present embodiment, it is possible to collectively perform the processing of reading the setting data and sucking up the inspection data while executing the meter-reading processing, so that the efficiency of the meter-reading work and the inspection work can be improved. Improve dramatically.

Next, the ID setting process and the ID changing process in the gas meter reading system according to the present invention will be described with reference to FIGS. 11 to 22.

<ID Setting Process> As described above, in order to wirelessly connect devices to each other, a unique ID for each device is registered in both the device itself and the device with which the device communicates. , The communication line is established on condition that the IDs of both parties are matched. Therefore, as an initial setting, an ID unique to each device and an ID unique to the device of the communication partner
Of course, if, for example, one device constituting the system needs to be replaced, the ID registration in the other device to be communicated with this device is also new. You have to change to the equipment.

Conventionally, this ID change requires complicated and specialized work of disassembling the inside of the device and changing the ID in the ID storage device using a dedicated setting device. In addition, there are some IDs that can be changed by exchanging parts, but in any case, the inside must be disassembled, and the work is extremely troublesome.

Therefore, in this embodiment, the gas wireless meter reading device 1 is used.
It is configured such that the ID setting registration can be performed accurately and easily by remote control from.

In the flowchart of FIG. 11, the operation starts when the power of the gas wireless meter 1 is turned on, and the "hidden command selection" screen as shown in FIG. 16 is displayed on the liquid crystal display 13 ( Step 1101). The two dotted lines on this screen are hidden keys, and when two hidden keys K1 and K2 are touched at the same time (step 11
03, 1105), the "device connection setting" screen shown in FIG. 17 is displayed on the liquid crystal display 13 (step 110).
7). On this "device connection setting" screen, two keys, device connection setting and alarm device connection change, are set, and when the device connection setting indicated by the dotted line in the figure is pressed (step 1
111), and the "ID input" screen as shown in FIG. 18 is displayed (step 1201).

The operator inputs the ID (4 digits) of each device in the four window portions surrounded by a square in the "ID input" screen. When the gas meter ID is entered, the memory unit 11
The alarm ID is stored in the display board memory of B (step 1
207), and when the ID of the alarm display board 7 is input,
The alarm ID is stored in the meter memory of the memory unit 11B (step 1211). When the execution key is pressed after inputting the ID (step 1213), the communication process is executed in the procedure as shown in FIGS.

After the communication processing is completed, as shown in FIG.
A message screen is displayed (step 1219). On this display screen, a message such as "The device connection has been completed" or "Device connection error of XXX. Please check." Is displayed. If the cancel key is pressed while observing this display, the process is terminated.

Next, the above communication processing will be described with reference to FIGS.
Explaining based on the flow chart of 1., the gas wireless meter reading device 1 serving as the setting device wirelessly transmits the connection setting command and the meter ID (step 1401). When the gas meter to be connected receives the connection command, at this time, the microcomputer gas meter 3 confirms whether it is its own ID,
If it is D, an ACK signal is transmitted (step 1501).
~ 1505). When the line is secured (step 1403), the gas wireless meter 1 that has received the ACK signal transmits the alarm device ID, which is the contents of the meter memory set in the memory unit 11B (step 1405). When the microcomputer gas meter 3 receives this alarm device ID (step 1507), the ID of the gas leak alarm device 5 to be connected is registered in the memory (step 1509). Then, the registration end command is transmitted to the gas wireless meter 1 side (step 1
511).

On the gas wireless meter 1 side, when the registration end command is received (step 1407) or when the registration end command is not received, after setting the meter connection end flag (step 1409), the next ID setting process is performed. Then, the connection setting command and the display board ID are wirelessly transmitted (step 1411).

When the alarm display board 7 to be connected receives the connection command, the alarm display board 7 confirms whether or not it is its own ID, and if it is its own ID, transmits an ACK signal (steps 1513 to 1517). ). Upon receiving the ACK signal, the gas wireless meter 1 transmits the alarm ID, which is the contents of the display board memory set in the memory section 11B, when the line is secured (step 1415). Alarm display board 7
Receives this alarm device ID (step 152)
1) The ID of the connected gas leak alarm device 5 is registered in the memory (step 1523). Then, the registration end command is transmitted to the gas wireless meter 1 side (step 152).
5).

On the gas wireless meter 1 side, when the registration end command is received (step 1417), or when the registration end command is not received, the display board connection end flag is set (step 1419), and then the wireless communication processing is performed. finish.

Thus, the ID of the alarm display plate 7 is registered in the microcomputer gas meter 3, and the alarm display plate 7 is also registered.
The ID of the microcomputer gas meter is registered in. Further, the ID of the gas leak alarm device 5 connected to the microcomputer gas meter 3 is registered in the selected microcomputer gas meter 3.

<ID Change Processing> Here, a case where the connection of the gas leak alarm device 5 is changed will be described as an example.

In the flowchart of FIG. 11, when the alarm device connection change shown by the dotted line in the figure is pressed from the device connection setting screen as shown in FIG. 20, as shown in FIG.
The "ID input" screen is displayed (step 1301).

The operator inputs the ID (four digits) of the gas leak alarm device 5 to be changed into the four window portions surrounded by a square in the "ID input" screen (step 1303).
